very active creature, which dashes about as soon as he emerges from the pupal case, and damages his wings (even when bred in captivity) before he can be caught. He has curious toothed antennae; the head and body are thickly clothed with fine hairs; the body has telescopic segments, capable of being protracted to double their ordinary length when impregnating the female enclosed in her cocoon. The wings are narrow, very lightly covered with scales, and without any very distinctive pattern. [Illustration: Plate XXIV.--LEPIDOPTERA.

Saunders’ Case Moth, _Metura elongata_, is our largest species; the larva constructs an elongate silken sack often up to 4 or 5 inches in length, broadest in the centre and tapering to both extremities; the outside is covered with short lengths of sticks nibbled from the food plant, or picked up during its wanderings. On an average these sticks are about as long as wooden matches, and are securely attached at irregular distances, the lower ones often extending beyond the silken tip. The caterpillar, of which only the head, thorax, and fore-legs can be seen, is a stout, naked, dull brown grub barred with black and reddish orange, measuring about 2 inches in length. The female moth differs so little from the caterpillar that it is hardly worth noticing, but the active winged male, with a wing expanse of about 2 inches, has the head and thorax thickly clothed with bright reddish orange down, and the dusky wings are lightly clothed with fine scales. Though the moth is a somewhat rare insect, the bag cocoon can be often found on a twig or attached to a fence, for in spite of the large house they carry they are great travellers. The Faggot Case-moth, _Entometa ignoblis_, forms a very different kind of portable home; the silken sack is covered with a coat of stout sticks which are generally cut from the gum trees and laid parallel to each other, and closely fastened to the silken surface, so that it reminds one of a bundle of faggots. They vary much in size and length; the larger measures up to 3 inches; one stick will be often found projecting an inch or more beyond the others; this is said to be a resting place for the male moth when seeking the enclosed female. She is of the usual obese form; of a general brown tint, the head and thorax creamy white spotted with black. The male moth with a wing expanse of 1¼ inches is of a uniform brown colour. The Leaf Case-moth, _Thyridopteryx hubneri_, forms a shorter oval silken sack averaging about 2½ inches in length and broad in proportion, covered
